TOEFL integrated writing: Chaco housing

The reading passage discusses the settlement in the Chaco Canyon by discussing the three theories to support the ideas of archeologists. However, the pofessor casts serious doubts on the ideas mentioned in the reading passage based on the evidences those are found in the Chaco Canyon.
First of all, the professor discards the theory of residential use of the Chaco Canyon, as the evidences from the site shows that there are very few fire places to support hundreds of families those could be accomodated in that place.
Second, the author believes that the structures were used for food supplying. However, the lecturer believes that the theory is wrong because there were large empty structures without any trace of maize or maize containers. So, emphasizing that there did not exist any remains of container, the speaker opposes the theory.
Third, the author in the passage demonstrates that the houses were used as ceremonial centers because of the remains of pots. However, again the speaker cast doubts on it by providing that archeologists have found lots of other materials too. They have found a large quantity of building construction materials and traces of leftovers of meals for construction builders. He believes that the buildings were used as a trash hill.
